[Review] Press Space

[Wingish]

I am very new to scripting, and this is my very first attempt at ruby scripting. I am trying to make a script that shows a image
saying "Press the space bar" Just like "Press Start" from other games. I know this is my first post, and I haven't been a member for very long, but I hope you other members can help me.

 # Press Space to enter the title screen

 class Scene_Space

  

     # Load the System database & create a new game   

  $data_system = load_data("Data/System.rxdata")

  $game_system = Game_System.new

   

     # Initialize some stuff

  @show = true

  @n = 0

  @picture_numb = 1

   

  # Define info about the image

  @sprite1 = Sprite.new

  @sprite1.bitmap = RPG::Cache.picture("Press-Space")

  @sprite1.opacity = 0

   

  

   # If SPACEBAR is pressed the player is sent to the title screen

     if Input.trigger?(Input::C)

       @show = false

       @n = 0

       @picture_numb -= 1

       end

      

       # Makes Press-Space visable 

         if @show == true

           @n = 255

       

            # Chooses the action required at the time

                     case @picture_numb         

            when 0

               $scene = Scene_Title.new

            when 1

               @sprite1.opacity = @n

         end         

           

  end

  

end  

 

Using this script I get an error with main on line 17 $scene.main

Thanks!

Well, that is what the website is about...

I guess. I hope to become a active member though!

What you need to do is wrap your arguments inside definitions, aka methods. Like this:

class Foo < SuperFoo

  def bar

    # code goes here

  end

end

  #--------------------------------------------------------------------------

  # Initialize the scene

  def main

        # Load the System database & create a new game  

     $data_system = load_data("Data/System.rxdata")

     $game_system = Game_System.new

      

        # Initialize some stuff

     @picture_numb = 1

      

     # Define info about the image

     @sprite3 = Sprite.new

     @sprite3.bitmap = RPG::Cache.picture("Press-Space")

     @sprite3.opacity = 0

   

       # Update graphics and input

  Graphics.transition

  loop do

     Graphics.update

     Input.update

     update

     if $scene != self

        break

    end

end

       # Discard your graphics when you leave this scene

  Graphics.freeze

  @sprite3.dispose

  end

      

  #--------------------------------------------------------------------------

  # ● Update the contents in this scene

  #--------------------------------------------------------------------------

  

  def update

     

      # If SPACEBAR is pressed the player is sent to the title screen

        if Input.trigger?(Input::C)

          @show = false

          @n = 0

          @picture_numb -= 1

          end

  

     

     # Update graphics

     @sprite3.update

     

  end

  #--------------------------------------------------------------

  # Uhmmmm some stuff

  #--------------------------------------------------------------   

    def transition

        

          # Makes Press-Space visable

            if @show == true

              @n = 255

          

               # Chooses the action required at the time

                        case @picture_numb        

               when 0

                  $scene = Scene_Title.new

               when 1

                  @sprite3.opacity = @n

            end        

              

     end

    

   end  

end    

EDIT
The only thing wrong is the image doesn't show.

Didn't you say you got an error? O_o

And well, the sprite (not a picture!) is shown, it's just not visible - here's your "error":

@sprite3.opacity = 0

You never set the opacity back to anything above 0.

 

[Wingish]

Now, the only problem is that, when I press the space bar c or enter it doesn`t send me to the title screen.

 

[BlueScope]

Note that THIS is what happens when you press the confirm button:

if Input.trigger?(Input::C)

  @show = false

  @n = 0

  @picture_numb -= 1

end

And this is what happens after the keypress check (wheather or not you pressed it):

if @show == true

  @n = 255

  case @picture_numb        

  when 0

    $scene = Scene_Title.new

  when 1

    @sprite1.opacity = @n

  end

end

So, to get to the title scene, @show would have to be true (you disable that with the confirm key input) and @picture_numb would have to be 0 (which, again, you kind of coutnerwork with your input check. Another suggestion: since you don'T really need a substraction here, use '= 0' instead of '-= 1' for the picture_numb setting.)
